Automotive sodium-ion starter battery developed for passenger cars, frequent engine restarting and customized H7 or PN3 battery replacement projects.
The Chalongfly 12V 40Ah sodium-ion start-stop battery is developed for passenger cars and compact vehicles that require reliable engine cranking and frequent restart capability.
The product is positioned around an H7 or PN3-style automotive battery format and can be customized according to the original battery tray, terminal layout, mounting structure and vehicle electrical system.
A smart battery management system monitors voltage, current, temperature and operating status. Cranking current, enclosure dimensions, terminals, protection parameters and branding are confirmed according to the target vehicle.
| Product Model | CLF-SSB-12V40Ah-H7 |
| Product Type | Automotive Start-Stop Battery |
| Nominal Voltage | 12V |
| Rated Capacity | 40Ah |
| Battery Chemistry | Sodium-Ion |
| Case Standard | H7 / PN3 Style |
| Cranking Current | Customized According to Vehicle and Engine |
| Battery Management System | Built-in Smart BMS |
| Cycle Life | More Than 3,500 Cycles |
| Main Application | Passenger Cars and Compact Start-Stop Vehicles |
Exact dimensions, weight, CCA, terminal layout and charging parameters are confirmed according to the final vehicle application.
Start-stop vehicles may restart the engine repeatedly during urban driving. The battery system must provide rapid cranking current while supporting repeated operating cycles.
The sodium-ion battery is configured to deliver short-duration high-current output for compatible gasoline or diesel engine starting.
The battery is positioned for vehicles that experience repeated engine shutdown and restart events during daily urban operation.
Cranking current and BMS parameters are selected according to engine displacement, fuel type, charging system and operating temperature.
Automotive batteries with similar capacity can use different housings, terminal arrangements and mounting bases. Fitment must therefore be confirmed against the original battery before production.
| Battery Tray | Length, Width, Height and Mounting Base |
| Terminal Layout | Positive and Negative Terminal Position |
| Terminal Type | Automotive Post or Customized Terminal |
| Hold-Down Structure | Customized According to Original Battery Tray |
The integrated BMS monitors the battery and provides protection against abnormal electrical and temperature conditions.
| Overcharge Protection | Over-discharge Protection |
| Over-current Protection | Short-circuit Protection |
| High-Temperature Protection | Low-Temperature Protection |
| Cell Voltage Monitoring | Cell Balancing |
| Start-Stop Passenger Cars Vehicles requiring repeated engine restart capability | Urban Taxis High-frequency daily urban vehicle operation |
| Ride-Hailing Vehicles Passenger fleets with frequent starting cycles | Compact Delivery Vans Stop-and-go delivery and service vehicle operation |
| Fleet Passenger Vehicles Customized batteries for vehicle fleet projects | OEM Automotive Projects Customized electrical and installation integration |
The sodium-ion battery can be developed as a replacement for a compatible lead-acid or AGM automotive battery after a complete vehicle compatibility evaluation.
| Vehicle Information | Brand, Model, Year and Start-Stop Function |

| Charging System | Alternator Voltage and Vehicle Charging Strategy |
Yes. It is positioned for compatible vehicles that require frequent engine restarting. Complete electrical-system compatibility must be confirmed before installation.
No. Exact dimensions, mounting bases and terminal layouts can vary. The original battery measurements must be confirmed.
A replacement battery can be developed after checking voltage, CCA, dimensions, charging system, terminal layout and start-stop control compatibility.
The cranking-current rating is confirmed according to the engine, original battery specification, minimum temperature and final battery design.
Please provide the vehicle model, engine information, original battery voltage, capacity, CCA, dimensions, terminal layout and charging-system voltage.
Send Chalongfly your vehicle model, engine specification, original battery CCA, dimensions, terminal layout and charging-system information. Our team will evaluate the application and provide a suitable sodium-ion start-stop battery.
